Abstract
This report describes results from the combined trawl and acoustic survey of the west coast South Island (WCSI), carried out from 20 July to 19 August 2012. The acoustic abundance index for spawning hoki in 2012 was 4% higher than the equivalent index from 2000 and slightly above the long-term average of the time-series. This survey was also the second in a new time series of trawl estimates for middle depth species from the WCSI, and trawl abundance indices are presented for 28 species.
